STAPLER.

Application tiled May 7,

My invention relates to a stapler and has for an object to provide a stapler having the body mounted on the base so as to be convcniently removed therefrom. and so arranged` may be used in conjunction with the base as a stapler and may also be removed -from the base and vscparublyused as atackcr. lnother object is to provide fthe.` stapler base with means for housing staple strips therein. A further object is to provide a base with a removable drawer "for receiving a staple container, and having means for frictionally retaining said drawer inposition and also for readily removing said staple container from said drawer.. Another object is to provide a base having a stapler block with an inset of hardened metal removably mounted therein. A further'objeet is to provide an improved adjustable gage mechanism lon the stapler. And another object is to provide a stapler having a body which has elements reyerslbly mounted thereon so as to ad'aptvsald body for use with the base as a stapler-and using the elements as stops, and said elements being allranged to be reversed and provide protruding claws.to engage materlal for drawing and holding the same, thus adaptlng the body to 'be used as a tackcr apart from the base.

Other objects .will appear hereinafter. The invention consists in the combinations and arrangements of parts hereinafter 5 on lline 2 2 of Fig. 1,

tuv

described 4and claime -The .invention will be best understood by reference to the .accompanying drawings forming a part -of this specification, and in Fig.- 1 is an elevational view, partly in section, showing the preferred form ot my invention; f e

Fig..2 -is a horizontal sectionalview,'taken showingT .the drawer and. staple container in position in the base; .Fig 3is a View similar to Fig. 2, with the fdrawer' and its contents removed: 'g `Figswl and. 5 are vertical cross-sectional' views', taken on' lines 4--4 and 5.-5 of Fig. 1; Fig. 6 is an elevational view showing a.

modified form-of stapler bod)7 mounted ion..

. Fig. A7 is a vertical `cross-sectional taken on line 7-7 of Fig. 6;

Fig. 8 is ano-elevational side view of the engage and chamber 17.

1925. serial 110.28545 v reversed to ada terial puller and tacker;

Fig. 9 is an inverted plan view thereof, partly broken away; and l -Fig. 10 is an elevational end view thereof. .'The form of construction illustrated in Figs. 1 to 5 inclusive comprises a\ stapler .body 12 removably mounted on a base'13 by means of a pair otlugs 14 on the base and a `hand screw 15,' with a knurled head 15', passing through said lugs and through a guide member 16 .for guiding the staple strips in the body member `12. j

The base is provided with a chamber 17 in which a drawer 18.is removably mounted 'and adapted to receive .a container or cartridge 19 provided with staple strips 20, as best shown in Fig. 2. This drawer is provided wit-h an opening 21 in the bottomto permit raising the container or cartridge 19 for convenient removal from the drawer. Said drawer is also provided with shoulders 22 and 23 adjacent the inner end and the outer end respectively, for engaging' the upper wall of. the chamber 17, to aid in holding the drawer in position when fully within the.l chamber butto permit convenient removal when -partly chamber, and. a spring 24 is further provided near the inner end of said chamber to press the drawer upwards and hold it frictionally in position' with the shoulders 22 and 23 firmly engaging the top of the chamber while the drawer is in its closed position. The drawer is thus firmly .held in its closed position, but after it 'is slightly withdrawn so that the shoulders 23 are moved outside ot' the chamber then it is more readily removable,.and when it is suiiiciently withdrawn to clear the spring '24 then it 1s very easily movable out of the chamber.

The base is provided with a stapler block 25 having'a recess 26 in its upper end and an opening 27-leading from the recess into the and having notches 29 in its top, is mounted .inr the recess with a close fit, and is adapted to be removed from the block, when said notches 29 are worn, by the'us'e of a punch or-.si-milar--artiele driven through the opening 27, the bottom 13 of the base 13 being removably mounted on' said base by the use of screws 13 as indicated in Fig. 2, thus providing access to said opening.

pt the body for use as a ma-v withdrawn from the An' inset 28 of hardened steel The gage4 mechanism provided on the.

for loosely engaging the guide rod 30.: andl a spring 35 is positioned between means on saidfarms for pressing said arms apart and to hold them clamped in position on the rod 30. Plates 36 and 37 are provided at the front of the arms to act as gages. are readily slidable' and adjustable on the rod by pressing their outer ends with the plates 36 and 37 toward each other.

The form illustrated iii Figs. 6 to 10 in-l clusive is adapted for use as a stapler in conjunction with the base. and' is also adaptedfor use as a tacker when separated from the base, the same as .in the preceding form, When the hand screw 15 has been removed;

lbut in this form the body is more. partiell-- larly arranged to adapt it for use as a tacker and also to be usedl in drawing material like screens for tac-king them upon the frame bars, and the like. This form includes the base 13, with the gage mechanism used in the preceding form omitted here ronL The body 40 is removably mounted )n said base by means of the hand screw 15 passing through lugs 14 and through the staple guide member 1G of the body .40, and this body cooperates with the. Astapler block 25 when used as a stapler. The gage means in this form includes plates or members 41 adjustably mounted at each side ot' the body by the use of slots 42 engaging'guide pins 43 provided on the body, and is firmly held in position by a screw 44 engaging through a slot 45. These slots are placed near one edge of the plate so as to adapt the plates as gages'when mounted in the manner shown in Fig. 6. Theplates are also provided with claws or teeth 46 which are used to engage. material as a screen or the like for drawing and holding the material in to position on the screen bar or'the like when the device is used as a tacker. The screen or similar .material may thus be drawn in position on the frame bars or the like, by using only the body 40, and by depressing the plunger in 4precise details of construction set forth, but desu-e to avail myself of such variatlons and the usual manner the staple is driven in position through-the screen or material into the Jframe. y

It is apparent from the above disclosure that either form of body may be-used Withl the base when employed as a stapler, and may be used by itself when employed as a tacker, and that the form of body shown in Figs. 6 to 10 is vvmore especially adapted for use as a tacker and to draw th'e material intov position upon a frame or the like and to hold it in such position by use of the teeth 4G. duringtthe tacking operation.

lVhile I have illustrated and described the .preferredl form of construction for carrying.

my invention into effect. this is capable of variation -and modification without. departure from the spirit of the invention. I, therefore, do not wish to be limited to the modifications as .come within the scopeot the appended claims. i

-I-laving described my invention what I claim as new and desire to secure by Letters 'Patent is:

1. In a stapler, a gage mechanism includ- L ing a guide member, a pair of armsI slidablc on said guide member and also slidable relatively to each other, and a spring forcing g5 said arms apart to clamp said guide member. l

2. A stapler comprising a guide rod. a pair of arms slidable on said rod, a spring arranged between said arms to force said arms apart and thus clamp said rod, and a gage plate on said arms cooperating with said .stapler to position work therein.

P. In a stapler, a base having a flanged seat, and gage mechanism including a guide member with a head firmly but. removably mounted in said fianged scat. and gage. means adjustably mounted on said member.

4. In a stapler, a base.' a guide rod on said base, and gage means including a pair of arms and a` .spring for adjustably clamping and holding the arms in position on said rod.

5. In a stapler, a base, la gudel rod on .said base, and gage means including arms having gage plates at the front and having openings wherein said rod engages and also to clamp said arms in having spring means position on said rod.

In testimony whereof I have signed my name to this specification.
